I remember being handed a score composed by Mozart at the age of eleven. What could I say? I felt like de Kooning, who was asked to comment on a certain abstract painting, and answered in the negative. He was then told it was the work of a celebrated monkey. 'That's different. For a monkey, it's terrific.'

The key to the mystery of a great artist is that for reasons unknown, he will give away his energies and his life just to make sure that one note follows another . . . and leaves us with the feeling that something is right in the world.

The whole problem can be stated quite simply by asking, 'Is there a meaning to music?' My answer would be, 'Yes.' And 'Can you state in so many words what the meaning is?" My answer to that would be, 'No.'

I think I should have no other mortal wants, if I could always have plenty of music. It seems to infuse strength into my limbs and ideas into my brain. Life seems to go on without effort, when I am filled with music.
